RADIATOR.

Appncaummed'aune 25, 191e. serial No. 306,615.

Be it known that I, GEORGE A. KILEY, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Radiators, of which the following is a specification.

This invention relates to a radiator and particularly pertains to a radiator of the type employed in connection with internal combustion engines for circulating the water through the engine :water jacket and for cooling same. f f

It is the object of this invention to provide a sectional radiator which embodies a unit adapted to be assembled together with any suitable number of complementary units 'to form a sectional radiator whereby the size and capacity of the radiator may be varied as occasion may require, and which is so constructed that a unit may be removed for repairs without necessarily putting the other units of the radiator out of operation.

Another object is to provide a radiator unit formed of a series of radiator elements which vcan be readily removed and' replaced for-repairs by personsv of ordinary skill thus not requiring the employment of experts when repairs are needed. and serving with the sectionalrfeature of the radiator to permit removal and repair of damaged units when remote from conveniences and where materials and labor are not available without discontinuing operation of the engine.

Another object is to provide a substantial detachable connection between the adjacent radiator sections which will permit of ready disconnection and reassemblage of the sections and by which a water tight joint will be assured in the connection.

Another object is to provide a radiator unit with a series of flexible zig-Zag tubes which will allow for expansion and Acontraction so as to largely prevent the tubes from being loosened at their connections by this cause.

Another object is to provide means'in the radiator for insuring a positive circulation of water therethrough.

A further object is to provide meansv for manually controlling the flow of water ,Y

through the radiator from a yremote point and for restricting the flow there-through to quicken warming up of the engine on ini tial starting thereof.

Other objects will appear hereinafter.

The invention is illustrated in the accompanying drawings, in which; f f

More 'specifically7 a, I), 0, cl, ande indicate separable radiator units, eac-h of which em- S, which are preferably rectangular-"in cross section with parallel front and rear walls, 9 and 10; the front walls of the ychambers of one unit being adapted to abut against lbodies'spaced superposed chambersyiand f the rear walls of an adjacent unit and sub-` stantially conformed thereto. Extended between the superposed chambers isy a series of spaced, substantially flat, zig-zag tubes7 il, arrangedl with their narrow edges eX- tending fto'the fi'ont andrear; these tubes having a width nearly corresponding tothe width of the superposed chambers. Thezigzag tubes ol'. one radiator unit are positioned to extend opposite the spaces between the tubes on ythe adjacent unit and the corrugations `on one r-row of tubes 'are preferably formed to extend Lin directions opposite the corrugations 4of the tubes on the adjacent row so` as to stagger the tubes inthe successive *rows relative to each other to form' broken or non-continuous air passages between the tubes throughout the depth of the assembled radiator units. By this construction, air flowing through the spaces between the tubes,ftraverses irregular passages and is brought into intimate contact with the surfaces of the tubes while k.being thoroughly agitated so asf-to effect a rapid cooling action.

An important feature of thisy invention resides in a means for detachably connecting adjacent units and forming communications between the upper chambers and between the lower chambers of contiguousv units. This means is particularly kshown in Figure and walls of the end units.

embodies a tube 12, having an out-turned iiange-13 on its outer end adapted to scat on and to be secured to anolfset flange 14e, formingthc margin of an opening in one of the walls 9 or 10. The tube 12 extends inwardly to project a short distance into the chamber 7 or 8 and has an inturned flange 15 on its inner end adapted to slidably encircle a tube 16 secured to the inner periphery of a ring 17 secui'ed to the offset margin 18 of an opening formed in the oppositer wall 9 or 10 and `havingan annular projection 19 adapted to 'the chambers as indicated at 21 in Figure 1 and the communication between thev adj acent lower chambers 8 is preferably disposed at one end thereof as indicated at 22 in Figure 1 with the communications between the successive units alternating from end to end 'so that water flowing through the lower chambers 8 Will traverse approximately the full length of each chamber. The communications 21 and 22 are preferably oblong in V' cross-section. and the communications 21 are vpositioned vertically so that the upper ends of the communications will be adjacent to the top wall of the chamber 7 so as to prevent formation of air pockets in the upper Y portion of the radiatorsand the con'imunications 22 are positioned to extend horizontally to cconomize space and yet afford a lare tubes 23, the ends of which open through the walls 9 and 10 and afford means whereby a series of the radiator units may be secured together by long bolts 2-'1 which extend through alined tubes 23 and engage the outer These tubes are arranged adjacent each of the communications 21 and 22 preferably at the corners of a rectangle so that when the bolts 24 aie tightened, the Vadjacent radiator units will be Vdrawn into tightl contact with each other and with the packing glands around each communication properly united to prevent leakage.

As a means of facilitating fiow of the water longitudinally of the lower chamber, a baffle plate 25 is disposed in each chamber 8 and extends lengthwise thereof with one end terminating in the end wall and its opposite end spaced from the other end of the chamber. This bafie plate is arranged to extend above the communication 22 and 0perates to prevent the direct fiow of water from the lower ends vof, the tubes into the communication 22 and directs the fiow of water from each tube to the end of the chambei opposite t-he communication 22 to the space beneath the baffle.

The forward end unit is fitted with an intake 26 fitted with the usual cap 27 through which intake the radiator may be filled andthe rear end unit has a tubular connection 28 for forming communication with the water jacket of an internal coind bustion engine in the usual manner; the rear unit being also fitted with an outflow conduit 29 leading to the lowerportionof the engine water jacket, as is common in radiator construction. AsV a means for restricting the flow of water through the radiator and water jacket, as on initial starting of the engine, to hasten preheating thereof, a 'butter- .fiy valve 8O is mounted in the conduit 29 and has a stem 31 extending through a packing gland 32 on the conduit 29. The outer end of the stein 31 is connected by a universal joint 33 to a turnable rod 34 extending to a point convenient to the reach of tlie'driver and the rod 34 is fitted with an operating" levei' 35 adapted to be engaged by a notched segment 36 by which the lever 35 may be held in various positions to retain the Valve V30 in any desired adjusted position. As a means for preif'enting complete cutting off of the How of water through the radiator, valve 3() is formed with a cut-away portion 37 which, when the valve is closed, forms an opening through, which a limited amount of water may pass. l

In the construction and assemblage of the radiator, a unit may be formed With any desired number of tubes and any desired number of the units may be assembled together according to the area of radiating surface Y desired.

In event either of the units become'damaged or leak from any cause, they may be removed and replaced by other units pending repairs. by forming the radiating surfaces of the zig-zag or corrugated tubes and forming the connection between the tubes and lille walls of the chambers 7 and 8 by soldered joints, these tubes may be readily removed and replaced by persons yof ordinary skill.

lVhilst I have shown and described a specific embodiment of my invention, it is obvious that various changes may be made in the details of' construction and the arrange'- nient of parts as may be necessary under .varying conditions without departing from 1,505,713 t t g3` nected units each of which embodies a pair 'to the inclined portions of the tubes on the of spaced superposed chambers and a Series adjacent unit,"l the adjacent upper chambers of zigzag fiexible tubes connecting said being in communication intermediate their 10 chambers, the adjacent zig-zag tubes on a ends and the adjacent lower chambers being unit beingl parallel to eac-l1 other with the in communication adjacent toy one of their series of tubes on one -unit arranged with ends. y
